Aaron Lehmann 1d274e9acf Change "service inspect" to show defaults in place of empty fields
This adds a new parameter insertDefaults to /services/{id}. When this is
set, an empty field (such as UpdateConfig) will be populated with
default values in the API response. Make "service inspect" use this, so
that empty fields do not result in missing information when inspecting a
service.
